Sounds like you live in a computer museum ;) How did you end up owning these?

I kept a handful of older computers, my ZX-81 still sitting somewhere, ZX-Spectrum, Apple Newton. My HP-48GX is used by my daughter. I have a dual CPU 486 machine... I doubt any of these is worth any $'s ...

I've always had an appreciation for odd hardware, and I've just tried to keep what I like of what I have.

Big fan of the Sinclairs - small, simple, yet filled with all sorts of neat tricks that made them inexpensive and simple. That cleverness makes for a great set of lessons to modern computer programmers and architects.

> I doubt any of these is worth any $'s ...

as always with a legacy $anything the price is for those who really want it.

I have Psion 3 (with a damaged screen cablr, but with a whopping 1MB SSD), it costs nothing, but people selling the working ones for more than $100

I think Linux dropped support for 486, right? That was the only thing I remember that supported dual 486.

NCR had a couple of SMP 486 boxen (NCR 3450, 3550 & 3600) that were supported by SCO Unix, SVR4 and (early) NT. I think they had support for OS/2. ALR, Unisys and Compaq made somewhat similar 486s with roughly similar OS support (although I vaguely recall the Unisys stuff was OEMed elseware). The support problem was 486 predated standardized SMP hardware (APIC), so it was all custom hardware.

A dual 486 is a very special beast.. What motherboard is that

tbh not sure. I'd have to dig it out of the crawlspace and have a look. But yeah, seems like those indeed are rare. Had no idea and I guess some chance I'm misremembering and it's a Pentium or something.
